THOMAS HIPWELL, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR TO THE PITTSBURGHBRASS COMPANY, OF SAME PLACE.

LAM P-HANGER.

SPECIFICATION forming part of Letters Patent No. 443,521, dated December30, 1890.

Application filed June 25, 1890. Serial No. 356,658. (No model.)

To all whom it may concern:

Be it known that I, THoMAs HIPWELL, a resident of Allegheny city, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Lam p-Hangers and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to, harps or hangers for lamps-that is, to a devicefor the suspension of a lamp from a ceiling or suitable bracket.

The object of my invention is to provide a suspension device in whichthe lamp-fou nt, together with the chimneysupported thereon, may beinserted within the hanger without having to tilt orincline said fountor-chimney, thus removing the liability of the breaking or cracking ofthe chimney by having the flame come in contact therewith on the tiltingof the same, cracking of the chimney by striking the shade, or spillingthe oil from the fount.

A further object is to provide a hanger which will support the fountfirmly in position and prevent any liability of its dropping whenroughly handled or jolted.

To these ends my invention comprises, generally stated, a lamphangerhaving a ring at the base thereof, lugs formed on the interior face ofsaid ring at opposite points, and a spring-bail having arms engagingwith said lugs and extending out beyond the same for the support of thefount resting in said ring.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich Figure 1 is a side view, partly in section, of my improved hangersupporting the lamp. Fig. 2 is a bottom view of the supportingring..Fig. 3 is a top view showing springarms in engagement with the lugs.Fig. 4 is a section on the line t 4, Fig. 3; and Figs. 5 and 6 aredetail views showing the two positions of the bail.

Like letters indicate like parts.

The hanger c is shown formed of wire bent to proper shape and having ahook or loop I) at the upper end thereof to engage with a suitable hookor loop secured to the ceiling or bracket. At the base of the hanger ais the ring 0, said ring being formed with the inwardly-extending flanged at the upperedge thereof. On the lower edge of the ring 0 and on theinterior face thereof are formed the lugs or cams c, at points directlyopposite each other, and each on the same side of the central line ofthe ring. The lugs e are rounded off, as at f, and are also providedwith the small indentations, as at g, forming a slight shoulder, for thepurpose more fully hereinafter set forth. A slight enlargement h isformed on the exterior of the ring 0 just beyond the lugs e, and withinsaid enlargement is formed the recess 2', in which the arm of thespring-bail j rests when not engaging with the lugs e. The bail j isformed of stiff spring-Wire and bent to the semicircular form, its endsbeing bent at substantially right angles to the bail to form the arms70, and the journals Z, which are bent at substantially right angles tothe arms It, being journaled in the bearings m in the enlargements h andat the upper ends of the recesses 2'. If desired, a second auxiliarybaila maybe employed to strengthen the support given by the bail j, the saidauxiliarybail n being jour naled, as at o, in the ring 0, and beingfurther provided with the loop p, adapted to engage with the bail j.

To provide for the supporting of the fount of the lamp within the hangerit has been customary to construct .said fonnts with a shoulder orannular flange encircling said fount at its point of greatestcircumference,

this flange being shown at r, and in the ordinary harp this flangeresting on top of the harp-ring.

To insert the fount within the hanger a the bail and its auxiliary bailn will be raised to the position shown in Fig. 2, when the fount held inthis position by one hand while the bail j is grasped by the other, whenby a quick movement of the hand enough force is exerted to overcome theresistance to the arms 71 due to the lugs cgwhereby said spring-armstravel over the faces of the lugs e and assume 5 the horizontal positionshown in Figs. 1, I l, and 6. The rounded faces j aid to renderthemovement of the spring-arms over said lugs more easy, and said armshaving passed said lugs spring back to the position above said lugs, butproject farenongh beyond said lugs to give a flrm support to the fonnt,the lower face of the annular flange 1' thereof resting on the arms 7;,which are SllppOltetl on the lugs c. The shoulders 1 form an abutmentfor the portion of the bail just beyond the arms 7: and further assistto render the engagement secure against any violent shak- 5 ing orhandling of the hanger. In this manner the fount is locked Within theringewith out having to tilt the fount or chimney in the slightestdegree, and as the upper edge of the annular flange r bears agaii'istthe flange (Z and the arms I.: bear against the lower face of the flanger the lamp is lirmly held against upward or downwardmovement in thering. The bailj also serves as a handle for the raising or lowering ofthe hanger, the tension of the spring-bail and its arms 7.: beingsufficient to prevent liability of displacement of said bail in ordinaryhandling.

To further supplement the resistance of the bailj to lateral movement,the auxiliary bail 12, which is mounted at right angles to the bailj,may be lowered, the loop 1) thereof engaging with the bail. To removethe fount, the operator grasps the bailj, and by applying force enoughto overcome the resistance due to the shoulders g the arms 7; resumetheir former vertical position within the recesses '2', removing allobstructions to the low ering of the fount from the ring 0, and it canthen be lowered directly from the ring.

What I claim as my invention, and desire to secure by 'Letters Patent,is

1. .in a lamp-holder, the combination, with the hanger, of a ring at thebase thereof, a bail journaled in the ring, and cam mechanism forcontracting the bail, so that the bail when so contracted forms asupport for the fount, substantially as and for the purposes set forth.

In a lamp-holder, the combination, with the hanger, of a ring at thebase thereof, said ring having lugs formed on the interior face thereofat opposite points thereon, and a bail journaled in the ring andprovided with arms engaging with said lugs and extending beyond the samefor the support of the fonnt, substantially as and for the purposes setforth.

In a lanai-holder, the combination, with the hanger, of a ring at thebase thereof, said ring having an in\vatally-extending flange at theupper edge thereof, and lugs formed on the lower edge of said ring atopposite points thereon, and a bail journaled in said ring having armsengaging with said lugs and ex tending beyond the same for the supportof the fount, substantially as and for the purposes set forth.

i. In a lamp-holder, the combination, with the hanger (t, of the ring 0,having the flange d, lugs e, and recesses :I, and the bailj, having thearms 7,: at an angle to the bail, substantially as and for the purposesset forth.

5. In a lamp-holder, the combination, with the hanger a, of the ring 0,having the lugs c, the bail j, having the arms 7:, and the auxiliarybail 21, having the loop substantially as and for the purposes setforth.

In testimony whereof I, the said THOMAS IITPWELL, have hereunto set myhand.
